Derive-macro-based generator that combines `Typestate` and `Builder` patterns.

A typescript express app with monadic middlewares and typestates.

Additional tuple traits to enable ergonomic types.

My talk at Rust Nation 2024 included a crate with some examples of how to use the Type system to your advantage.

Examples of the Typestate pattern in Rust
